IPAPER-ROLIa-SUPPORTING MECHAN ISM.

To all whom it may concern:

Be it known that we, HENRY A. Wrsn Wool) and JOHN A. ISBELL, citizens of the United States, said WOOD residing at New York, county and State of New York, and said ISBELL residing at Middletown, in the county of Orange and State of New York, have invented a new and useful Paper-Roll- Supporting Mechanism, of which the following is a specification.

This invention relates to the spindle for carrying a paper roll for use on a web printing press. Heretofore so far as we are aware, bearings have been fixed on the brackets which support the web rolls and spindles and they have been arranged to be removed from the bearings.

The principal object of this invention is to provide a construction in which the spindle will not have to be removed from the bearings when taken from the machine, so that the bearings shall always properly fit the spindle and so that the placing of the paper roll in position may be facilitated. A further object of the invention is to provide improvements in the adjustment of the cones for fastening the paper rolls to .the spindle. The invention also involves improvements in details of construction and combinations of parts as will appear hereinaften.

Reference is to be had to the accompany- "ing drawings in which- Figure 1 is a side view of the end of a web printing press showing several rolls supported thereon, and also illustrating two of the roll spindles in transverse section;

Fig. 2 is a detail elevation of a paper roll mounted on its spindle on an enlarged scale showing the brake Fig. 5 is a side'view on enlarged scale of a portion of the supporting brackets and locking device; and

Fig. 6 is an enlarged sectional view of the bracket on the line 6-6 of Fig. 1.

Fig. 1 shows three web rolls A in their final positions on the machine, and shows Specification of Letters Patent.

Application filed June 5, 1913. Serial No. 771,856.

in dotted lines the initial positions of two of these rolls when first placed on the brackets 10 which are carried by the frame 11 of the web press. The bottom bracket 10 is constructed differently as is well understood in this art to receive a roll directly from the floor. The upper brackets, however, are each provided with a substantially horizontal surface 12 having a projection 13 at its outer end and a depression 14: at its inner end. By means of a series of studs 15 a track or guide 16 is mounted at a distance from the side of each of these upper brackets. It terminates in an inclined surface 17 adjacent to the depression 14. Above this depression 14 is a cap or clamp 18 pivoted at 19 and provided with a spring-pressed latch 20 adapted to engage a pin 21 on the bracket.

The paper roll carrying spindle 25 is shown as provided with a key-way 26. In this fit loosely keys 27 each mounted on an inner ball-race support 28. Each of these carries the inner member 29 of a ball-race and is provided with screw-threads on the end for receiving a pair of nuts 30 and 111 outer housing 32 is provided having a seat for the outer member of the ball race and a seal 33is arranged as usual in the open end of this housing and fixed thereto. This housing is of a substantially cylindrical form outside, but has flanges 3 1 at its edges. This housing constitutes a roll adapted to fit on the surface'12 and in the depression 14 and to be engaged and held bythe cap 18 when the latter is in locked position as shown in Fig. 1.

On one end of the spindle 25 is located a circumferential groove 36 at a proper distance from the adjacent housing 32 to engage the track 16 when the housing of the bearing is rolling along the surface 12. The outer end of this track is depressed as shown in Fig. 1. It will be obvious that when the roll is placed on the two brackets in the dotted line position the engagement in the groove 36 will guide the roll properly into the depression 14. Then the cap can be brought down into fastening position. This afi'ords a convenient and quick means for placing the paper rolls. in position and-proof the track vides an easy running support for them. Moreover, as these hearings are removable with the Web roll spindle, they are always properly located thereon.

It is to be understood that the key 27 of each of the bearings fits loosely in the keyway 26 so that the spindle can be moved longitudinally for the purpose of properly registering the paper roll. In spite of this fact, however, the spindle is properly guided into place on the brackets by the brake pulley itself as has been stated already. The side register can be made by means of a movable disk 56 adapted to enter the groove 36 when the spindle is in proper position in the press. The track 16 guides the drum into proper position to cause the disk to enter the groove.

For the purpose of holding the paper roll and securing it properly in position the following mechanism is provided. A split cone 40 is arranged With a key 41 passing loosely into the key-way 26 and a bolt 42 is provided for clamping this cone in position on the spindle. Ordinarily this cone is secured in one position and is not adjusted thereafter so it may be considered as a fixed cone. The key 41 projects beyond "the conical surface of the cone.

Near the other end of the spindle and facing the cone 40 is an adjustable cone 44. This cone is provided with a circumferential shoulder 45 at the back. Over it is mounted a sleeve 46 having a projection extending down over the shoulder and free to turn. Fixed to the inside of this sleeve is a nut 47. A collar 48 back of this nut is provided with a screw-threaded projection entering thenut. This collar is split and provided with a bolt 49 for clamping it in position on the spindle. In practice this collar is moved to a convenient position on the spindle taking the movable cone 44 with it.

Then the collar is fastened to the spindle.

The sleeve 46 can then be turned to adjust the cone 44 to proper position along the spindle. This cone 44 is provided with a key 50 which projects into the key way loosely and prevents the rotation of the cone. It also projects beyond the conical surface of the cone.

The paper spindle itself is provided with ahollow core 51 having a sheet of metal 12 at each end surrounding its outer surfaces and shaped on the interior to fit the two cones. At each end it is provided with a slot 53 for receiving the keys 41 and 50. Tn thisway a quicklyadjustable arrangement is provided for fastening the paper roll to the spindle and yet one which can be adjusted as a whole longitudinally of the spindle when required.

Although We have illustrated and described a single specific embodiment of the invention, we are aware of the fact that aaaaeoe many modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims.
